Map Datum Selection

Maps and charts are based on a survey of an area covered by the map
or chart. These surveys are called Datums. Maps using different da-
tums will show the same latitude/longitude in different locations.
All datums are named. The GPS system is based on the WGS-84 da-
tum, which covers the entire world. Other datums may also cover the
entire world, or just a small portion of it. By default, your unit uses the
WGS-84 datum. It, however, can show your position using any of 191
datums. Different datums can be selected. To change the datum:
1. Press
MENU
2. Use ↓ ↑ to select the desired datum, then press
3. To return to the last page displayed, press
A list of the datums used by this unit is in the back of this manual.
